Question

I have this piece of code:

static char szTop[] = "iMsg             wParam              lParam";
static char szUnd[] = "____             ______              ______";
static char szFormat[] = "%-16s%04X-%04X        %04X-%04X";
static char szBuffer[50];
static HWND hwndButton[NUM];

And it gives me error :

error C2143: syntax error : missing ']' before ';'
error C2143: syntax error : missing ';' before ']'

Another code is:

for(i=0;i<NUM;i++)
    hwndButton[i] = CreateWindow ( "button", button[i].text, WS_CHILD | WS_VISIBLE | button[i].style, cxChar, cyChar * (1+2*i), 20*cxChar, 7*cyChar/4, hwnd, (HMENU) i, ((LPCREATESTRUCT) lParam )->hInstance, NULL );
return 0;

And this gives me error:

error C2146: syntax error : missing ')' before identifier 'i'
error C2059: syntax error : ';'
error C2059: syntax error : ')'
error C2146: syntax error : missing ';' before identifier 'hwndButton

I have defined the required things previously as:

static char szTop[] = "iMsg     wParam              lParam";
static char szUnd[] = "____         ______      ______";
static char szFormat[] = "%-16s%04X-%04X        %04X-%04X";
static char szBuffer[50];
static HWND hwndButton[NUM];
static RECT rect;
static int cxChar,cyChar;
HDC hdc;
PAINTSTRUCT ps;
int i;
TEXTMETRIC tm;

Answer 1

For that first one, this can be caused by not having a definition in place for a type or macro, most likely HWND or NUM.

For the second one, it’s complaining about the use of hwndButton before defining it, simply because of the first error – that variable was never defined because the statement that tried to define it had that earlier error error.

First, verify that you have included the correct headers. I think it’s in windef.h but is usually included by the windows.h header file.

Second, ensure that NUM is actually defined somewhere.

I think it’s probably the NUM one simply because one of the errors comes from the for loop statement, where windows.h stuff is not used but NUM is.
